I post this here (and on Mosio, and linked to on Twitter) in hopes of an answer.  We see these things towed by 18-wheelers up and down I-20, but don’t have the slightest idea what they are.  They have no company identification, and no other identifying marks that we’ve found.  Searching google for "big plastic container" doesn’t help much.  Any ideas?

UPDATE: Wow.. Took less than 20 minutes.. Thanks you interwebs!!  The answer seems to be a "Wind Turbine Nacelle" (from multiple sources).  Given that these were heading West on I20 through Mississippi and there’s a huge Wind Farm under construction in Texas, it makes sense.  Plus, I found a great pic of one of these in action at the AWEO Website.
